So, is Alex Rodriguez the current male in her life? She’ll only say: “I grew up with the Dodgers, but now I’m a Yankees fan.”

In Cameron’s next movie Bad Teacher, she stars opposite her ex-boyfriend Justin Timberlake. Was it awkward? “Justin and I have laughed together for years. He is the funniest guy; you’ve seen the stuff he does on SNL,” she says.

So, how has fame affected the Knight & Day star’s life? “People always say, Oh, you haven’t changed at all, despite the fame,” she says. “But I believe that fame makes you become who you are more clearly.”

She adds: “When all the doors are open for you, you have to set boundaries for yourself. If you don’t have a good upbringing, the danger is that you’ll take advantage of those limitless opportunities, and then you lose your s***.”

And as for being snapped in private moments, such as emerging from A-Rod’s Manhattan apartment, she shrugs, “I’m not going to spend my energy worrying about that. I’m just going to live my life, because I know who I am, what I’m doing, and who I’m doing it with.”

Cameron’s workout regime is as effortless as everything else in her life. “Exercise for me is like eating, sleeping, and breathing,” she explains. “I’m consistent, and when I’m not consistent, it shows up on my body. I get really skinny, and I know it might sound like, ‘Well, good for you.’

“But the body that people talk about is not me trying to stay slim, it’s the one where I work hard to keep weight on me.”

And the 37-year-old has no fear of aging. “Oh, I feel so much more attractive now,” Cameron insists. “A thousand percent. I’m appreciating my skin and my wrinkles and all those things because you cannot stop aging, you can’t.”
